Hello,
I am working with the F28035 control card with the DRv 8312 board with the PM_Sensorless code. I would like to implement regenerative braking by using the inverter topology already present on the board, to form it as a DC/DC boost converter?
How to know which commutation/switching state the motor (i.e. PMSM) is in at a particular time? I know with the BLDC sensored code, it actually shows you in the BLDC pwm code when the commutation ptr is a certain value, which phases would be energized.
With the PM_Sensorless code, i know it uses SVPWM to generate the PWMs, but it does not (or i haven't realized yet) how to actually know which motor phases are energized. This info is critically needed for my project I believe.
Can I receive some guidance please?
